Drive through the canal streets off Floramar Terrace or the grid of homes east of US-19, and you'll notice a pattern: a lot of Bayonet Point's housing stock went up during the same window, roughly the mid-1970s through the mid-1980s, when this stretch of Pasco County filled in fast as an affordable waterfront and boating community. That means a large share of homes are now carrying original or first-replacement siding that's 30, 40, even 50 years old. Materials that were standard then — aluminum panels, T1-11 plywood siding, early-generation vinyl — were never built to last this long, and they're showing it: chalking aluminum, delaminating plywood seams, buckled vinyl that's gone brittle in the sun.
We get called out to a lot of these same-vintage homes, and the siding failure looks almost identical from one street to the next. That's not a coincidence — it's a whole neighborhood aging out of its original exterior at roughly the same time. If your siding is original to the house, or it's a mid-90s replacement that's now pushing 30 years itself, you're not early to this conversation. You're right on schedule.
Before we talk replacement, it helps to know what's underneath your current siding and why it's giving out:
In every case, the fix isn't a patch — it's a full replacement, because these materials fail as a system, not in isolated spots.
Alpine Exteriors installs James Hardie fiber cement siding exclusively. We don't offer vinyl, and we don't offer engineered wood products like LP SmartSide. That's a deliberate standard, not a lack of options, and here's the reasoning:
| Factor | Vinyl / Engineered Wood | James Hardie Fiber Cement |
|---|---|---|
| Moisture behavior | Vinyl can warp under sustained heat; engineered wood swells and can rot at damaged edges | Cement-based composition resists moisture intrusion and doesn't swell or rot |
| Sun/UV over decades | Vinyl fades and becomes brittle; color is molded-in and can't be restored | ColorPlus factory finish is baked on and warrantied against fading and chipping |
| Pest resistance | Engineered wood is an organic substrate insects can still exploit if the coating is compromised | Non-organic composition gives pests nothing to feed on |
| Installation sensitivity | Forgiving of minor installer error, but that's partly why it's easy to install badly | Requires correct fastening, clearances, and joint treatment — we follow Hardie's published install specs exactly |
| Warranty structure | Prorated after the early years on most vinyl lines | Non-prorated limited warranty on the plank; separate finish warranty on ColorPlus color |
None of this is a knock on every vinyl or engineered-wood job out there — plenty are installed fine and serve their purpose. It's simply that after years of tear-offs on homes exactly like the ones in this neighborhood, fiber cement is the one material we're comfortable standing behind for the long haul in a Gulf Coast climate.
Bayonet Point sits on a network of canals that feed out toward the Gulf, and a good share of homes here are on or near the water. That waterfront setting is a huge part of the neighborhood's appeal, but it also means constant humidity, salt-tinged air moving in off the canals, and prolonged damp conditions under eaves and around window trim compared to inland Pasco homes just a few miles east. Materials that hold up fine in a dry inland climate can degrade noticeably faster here.
James Hardie's siding for this region is manufactured to their HZ5 climate specification, engineered specifically for humid, moisture-heavy climates like ours — as opposed to their HZ10 formulation built for freeze-thaw regions up north. That distinction matters more here than most homeowners realize; siding sold nationally isn't always matched to Gulf Coast humidity, and getting that wrong shows up as premature failure ten or fifteen years down the line, not on day one.
Siding replacement season in Bayonet Point runs on the same clock as hurricane season. We recommend scheduling replacement work outside the peak June–November window when possible, both for material lead times and so your home isn't mid-project when a storm system tracks toward the Gulf. Properly installed Hardie siding, fastened per manufacturer wind-load specs, holds up well through tropical storm conditions — but "properly installed" is doing a lot of work in that sentence, which is why fastening pattern and clearances aren't a place to cut corners.
Depending on your home's style and what you're replacing, we typically work with:
All of it comes in Hardie's ColorPlus factory-finish palette, which means the color is baked on before the boards ever reach your house — it holds up better than field-applied paint and comes with its own finish warranty separate from the substrate warranty.
A full siding replacement isn't just pulling off old panels and nailing up new ones. Our process:
| Factor | Why It Matters |
|---|---|
| Sheathing condition | Homes with long-term water intrusion often need OSB or plywood sheathing replaced before new siding goes on — this is discovered at tear-off, not before |
| Home size and stories | Square footage and access (single story vs. two-story) both affect labor time |
| Trim and detail work | Homes with more corners, gables, and window trim take longer than a simple rectangular footprint |
| Product selection | Standard HardiePlank vs. shingle accents vs. upgraded trim packages carry different material costs |
| Removal and disposal | Aluminum and old vinyl haul-off is straightforward; damaged plywood with hidden rot can add scope once it's exposed |
Every one of these varies enough house to house that we don't quote a number sight unseen — an honest estimate means walking the exterior first.
If your Bayonet Point home is due for new siding — whether it's original aluminum from the 70s, tired T1-11, or vinyl that's had enough sun — we'd be glad to take a look and walk you through what James Hardie fiber cement would mean for your specific house. Reach out for a free, no-pressure estimate using the form below.
Most single-story homes take one to two weeks from tear-off to final trim, depending on size, how much sheathing repair is needed, and weather. Two-story homes or those with a lot of trim detail can run longer. We'll give you a realistic timeline once we've seen the house in person.
Ask for their Florida license number and verify it directly with the DBPR rather than trusting a business card, ask what siding brand they install and why, and get proof of liability and workers' comp insurance in writing. Also ask how they'd handle discovering rotted sheathing mid-project, since that's a common surprise on older homes here.
Hardie manufactures siding in two climate-specific formulations — HZ5 for humid, moisture-prone regions like the Gulf Coast, and HZ10 for northern freeze-thaw climates. Installing the wrong formulation for the region can lead to premature wear, so we only use HZ5 product for Bayonet Point homes.
Yes — replacing old aluminum or plywood siding is also a chance to correct any gaps in the weather-resistant barrier underneath, which often wasn't installed to today's standards on 1970s and 80s construction. That barrier layer does more for keeping moisture out than the siding material itself.
Scheduling before peak season (June through November) is generally better, since properly fastened Hardie siding needs time to be installed correctly rather than rushed, and canal-front homes see more humidity exposure while older siding continues to fail. We recommend not waiting until storm damage forces the decision.
